Customer Question

I have a Cadillac SRX with 112k miles on it. It is hesitating when I drive. It almost feels like it is losing power for a split second. It does it more when I'm going in the 45-55 mph range. When I'm accelerating strongly or going 60+ mph, it rarely does it.I've only had the car for 4 months. Purchased it from a private party so I don't know much about prior care.Any ideas?

You may have quite a few different things going on. You may be feeling an ignition system issue such as a loss of spark due to a momentary loss of cam or crank signal, it could be an electronic throttle control issue, if you see the RPM's climb but the power isn't transmitted to the wheels then you have a transmission concern.

The first step in diagnosing the problem is to see if any fault codes are setting. Have you checked for codes?
